Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459528, here are decompositions:

11 + 31459517 = 31459528
29 + 31459499 = 31459528
41 + 31459487 = 31459528
71 + 31459457 = 31459528
179 + 31459349 = 31459528
239 + 31459289 = 31459528
311 + 31459217 = 31459528
509 + 31459019 = 31459528

Showing the first eight; more decompositions exist.
